Boxers who fought both brothers.

Qawi lost a UD to Michael Spinks and then beat the brakes off of a shot Leon Spinks live on ABC. I'll never forget watching him laugh and taunt Leon while punishing him him the corner.

 

Ali beat Mac and Bob Foster but none of the three were related.

 

Dwight Muhammad Qawi and Michael Spinks both fought Eddie Davis and Johnny Davis.

 

- Austin Trout fought both Charlo brothers.
- George Groves fought both Paul and Callum Smith.
- Daisuke Naito fought Daiki and Koki Kameda.

I wonder if someone fought more than 2? Here, I suspect there might not be one.

 

Dwight also fought both Spinks brothers.

 

Joe Louis vs Max and Buddy Baer.

 

Didn’t Joe Frazier take on Muhammad and Rachman Ali at the same time in a studio interview?

 

Byrd fought both Klitschkos...

 

Louis Curtis and Kelvin Seabrooks fought both Canizales brothers

 

Roberto Duran fought Adolfo and Edwin Viruet. He also fought both Hagler and Robbie Sims.

 

Billy McGrandle was stopped by the Pimental twins back-to-back.

 

Jack Smith fought 3 of the Sands brothers: Alfie, Clem and Richie.
Freddie Mueller fought Frankie, Billy and Pete Petrolle.
And Stanislaus Loayza fought the same 3 Petrolle brothers.

... probably several other such examples - though none immediately springs to (my) mind.

 

Amazing, thanks!

 

Vic Darchinyan fought and stopped Glen Donaire, and then got KO'd twice by Nonito Donaire.
